UNITED STATES PATENT OFFICE.

CHARLES CARR, OF PHILADELPHIA, PENNSYLVANIA.

ARGAND LAMP ADAPTED TO BURN SPIRITS OF TURPENTINE, GAMPHENE, 8w.

Specification of Letters Patent No. 2,514, dated March 28, 1842.

To all whom it may concern:

Be it known that I, CHAnLEs CARR, of the city of Philadelphia, in theState of Pennsylvania, have invented an Improvement in Lamps for BurningCamphene, Pure Spirits of Turpentine, and other Articles of a LikeCharacter; and I do hereby declare that the following is a full andexact description thereof.

The principal peculiarity in my improved lamp is in the manner ofconstructing and arranging the burner and wick holder so as to adapt itto the burning of camphene &c. The wick holder is to be raised andlowered in a manner resembling that adopted in.the older fashionedArgands lamp, in which a rack and pinion were employed for that purpose;but in my lamp the wick holder remains permanently within the spacebetween the two tubes which constitute the burner; as, although itslides freely up and down within said space, it is not to be removedfrom it for the purpose of renewing the wick, nor, indeed, is it capableof being removed, there not being any slot, or opening, through theupper portion of the outer tube of the burner, as in the originalArgands lamp; said tube being made continuous at its upper end, thisbeing necessary to adapt it to the burning of the essential oils. Thewick holder, in my lamp, not being removable, is made of such length asto cause it when raised to its greatest height to project to asufficient height above the top of the burner, for the reception, andsecuring, of the wick thereon.

In the accompanying drawing, Figure 1, is a perspective view of one ofmy lamps, A, being the ordinary reservoir of the material to be burned.

B, is the burner, which is made of greater length than usual, to adaptit to the peculiar construction of my wick holder. The burner isconnected with the reservoir by the flat,

tubular space, C, C, which communicates With the reservoir and with theburner, the outer tube of theburner having a slot, or opening, along itfrom the lower end to the part where it is connected with the upper endof the flat tube C, C, this being neces sary to the raising and loweringof the wick holder.

D, D, is the rack and pinion for raising and lowerlng the wlck, whlchrack is connected with the wlck holder by means of the wire F.

Fig. 2, represents the wick holder, the rack, and the wire by whichthese two parts are connected together, as they would appear if removedfrom the lamp.

D, is the rack, and E, the wick holder, which are connected together bythe wire F, F; the wick Gr, G, when placed on the wick holder, extendsdown to the dotted line H. The range of the rack D, is such as tocorrespond with the proper length of the wick, so far as it is to beburned; but when the wick is to be renewed, the wick holder can beraised by taking hold of the wire F, so that the part above the dottedline H, will project above the burner; the part F, of the connectingwire will then be in contact with the upper end of the flat, tubularspace C, C, Fig. 1, and cannot be raised any higher. When the wickholder is forced down, its lower end will be in contact with the fluidto be burned. The button I, Fig. 1, is to be raised and lowered, so asin combination with the raising and lowering of the wick, to regulatethe combustion, as in other lamps for burning camphene.

Having thus described the nature of my improvement in the lamp forburning spirits of turpentine, camphene, and other essential oils, whatI claim therein as new, and desire to secure by Letters Patent, is

The manner in which I have arranged. and combined the rack and pinion,the wire F, F, the wick holder and the burner, so that the outer tube ofthe burner shall be continuous at its upper end, while the wick holdershall have the requisite play up and down, not only for the purpose ofcombustion, but also for the supply of a new wick when requisite, said.wick holder being permanently retained within the burner; the respectiveparts being constructed and operating substantially as herein describedand made known.

CHARLES CARR.
